SPRING-HEEL HVORSESHOE.

SPECIFICATION forming part of Letters Patent No. 637,219, dated November '14, 1899-. Y

Application filed August 1, 1899. Serial No. 725,802. (No model.)

To aZZ whom it may concern:

Be it known that 1, JAMES TRAINER, a citizen of the United States, residing at Peniel, in the county of Gallia and State of Ohio, have invented a new and useful Horseshoe, of which the following is a specification.

This invention relates to horseshoes, and particularly to a yielding heel-calk attachment therefor of a specific form and applied to the ordinary shoe Without material preparation or departure from the primary con struction.

In attaching a spring-heel device to a horseshoe as heretofore practiced the usual custom pursued has been to fasten rearwardly-projecting upstanding spring-arms on the upper surface of the shoe, which become interposed between the hoof and the shoe and entirely devoid of call; features, and, further, to recess the under rear end or heel of the shoe and set the front end of a calk attachment therein, thus bringing it so close to the adjacent part of the shoe as to make the space for play insufficient and the spring action of little or no avail.

One object of the present construction is to provide a spring-call; attachment on the under side of the heel of the horseshoe, so that it will normally stand downward at an oblique angle and when compressed bears closely against the adjacent part of the shoe, and thereby eases the movement of the animal, lessens fatigue, and under comparative conditions encourages an increase in the distance of travel, and also cushions the tread, particularly on stony roads or non-yie1ding surfaces.

A further object of the invention is to utilize a yielding calk attachment on a horseshoe without detracting from the effective biting or gripping purchase of the calk, and thereby reserve the sustaining properties of the shoe, especially for draft purposes.

These objects and the disadvantages heretofore encountered are intended to be attained and overcome, respectively, by the construction illustrated in the accompanying draw= ings, wherein- Figure 1 is a perspective View of a horseshoe in inverted position and embodying the features of the invention. Fig. 2 is a side elevation of ahorseshoe, showing the spring heel calk pressed against the adjacent portion of the shoe. Fig. 3 is a detail perspective view of one of the improved heel-calks.

Similar numerals of reference are emplo'ye to indicate corresponding parts in the several views. I The numeral 1 designates a horseshoe of ordinary form and having atoe-calk 2 applied to the under front portion thereof in any preferred manner. The heel ends 3 of the shoe have their under portions cut away or rounded at opposite edges, as at 4, and slightly inclined in an upward direction, extending gradually without break from the under surface of the shoe.

The under rear portions of the shoe have the improved yielding calks applied thereto, and each of the said calks consists of a rest 5, from which extends a shank 6, having a terminal calk 7. The rest 5 has an upper face 8 in the same plane as the under face of the shoe to which it is applied, and the under surface of said rest is inclined rearwardly and downwardly in a regular plane to a point 9, where the shank 6 begins. This gives the rest 5 a V-shaped form, with its reduced end at the front, and in applying the calk the said rest is riveted or welded to theshoe, it being understood that the downward obliquity of the calk will be uniformly maintained.

From the point 9 on the rest theshank commences and has a slightly greater or more abrupt angle of deflection than the said rest. The under surface of the shank 6 terminates at the forward shoulder of the calk 7, said shoulder being continued partially around the opposite side portions of the shank, and the latter is reduced and given a substantially rounded contour. The under face of the calk 7 is flat and preferably rectangular in form, thus producing front and rear and opposite end biting edges, and the upper portion of the shank 6 is continuous with the upper portion of the call: and substantially straight, so as to bear against thefunder cutaway portion of the heel of the shoe. When pressure is brought to bear on the Shoe at the rear, the bend of the shank 6, which is preferably of spring metal, Starts at about the point 9 of the rest 5 or at such point in the ried out.

upper portion thereof which begins to clear or stand out from the under face of the shoe, and this bending action continues regularly until the upper straight merged surfaces of the shank and calk are brought fully in contact with the under part of the cut-away heel of the shoe and which has a slight upward inclination. When the shank is disposed or pressed into the position just explained, the under surface of the calk 7 will be about on a level with the biting edge of the toe-calk 2, and by these means the animal is permitted to have a full-foot contact with the surface of the road-bed or other surface over which he moves. When the shank is brought up in this manner against the heel of the shoe, it will be observed that the under surface of the calk will have a firm bearing position given it and the sustaining function of such device, as in ordinary horseshoes, is fully car- Both calks stand in the same relation with the shoe and have similar operations, and when pressure is removed therefrom or at the time the animal lifts his foot they assume their normal position, which is at a downward oblique angle, as previously stated. The upward pressure of the shanks of the opposite calks will be equaland regular, and though a resistance is met with when the shanks are brought to bear against the under portions of the heel ends of the shoe it will take place at any time when the animals foot is fully down and will break the sudden jar that ensues at this point in ordinary shoes.

At times it might be more convenient to form the calk attachments integral with the heels of the shoe; but the separate arrangement of such devices is preferred.

Changes in the proportion, size, and details of construction may be resorted to to accommodate the various applications and without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed as new is- A horseshoe having the under portions of the heels reduced at opposite edges and cut away at a slight upward angle, combined with calk attachments comprising rests applied to the under sides of the shoe in advance of the heel ends, the lower sides of the rests being oblique and having downward and rearward angles and continued into shanks which have a greater similar angular deflection and terminating in calk projections, the upper portions of the shanks being straight and continuous with the upper plane of the calks, said shanks having a substantially rounded contour in cross-section and the calk projections extending laterally therefrom, the rests of the calks being applied to the under fiat surfaces of the shoe.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JAMES TRAINER.
